Abstract
The stability of the dyes which are obtained after processing a color photographic material is improved by the addition of a polyvinylcaprolactam.
Claims19
A color photographic material which comprises at least one light-sensitive silver halide emulsion layer, and which, in at least one layer which contains a color coupler, contains at least one homo- or copolymer which comprises a monomer unit of formula (II)
- wherein the monomer unit (II) amounts to at least 10% by weight in copolymers, wherein the material contains at least one yellow coupler, at least one magenta coupler and at least one cyan coupler and wherein the material can be processed without intensification.
A color photographic material which comprises at least one light-sensitive silver halide emulsion layer, and which, in at least one layer which contains a color coupler, contains at least one homo- or copolymer which comprises a monomer unit of formula (II)
- wherein the monomer unit (II) amounts to at least 10% by weight in copolymers, and
- wherein the color coupler corresponds to formula (I)
- wherein
- R11 and R12, independently of each other in each case, are alkyl, or R11 and R12 can jointly form a ring system,
- R13 is H or has the meaning of R11 or R12,
- R14 is H, alkyl or halogen,
- X11 is halogen or alkoxy,
- X12 is acyl, acylamino, halogen, sulphonamido or sulphamoyl,
- Z11 is a group of formula
- and Q11 is an organic group for the completion of a 5- or 6-membered ring.
A color photographic material which comprises at least one light-sensitive silver halide emulsion layer, and which, in at least one layer which contains a color coupler, contains at least one homo- or copolymer which comprises a monomer unit of formula (II)
- wherein the monomer unit (II) amounts to at least 10% by weight in copolymers, and
- wherein the coupler corresponds to one of formula Ib or Ic
- wherein
- R15 and R16 are methyl or R15 and R16 can jointly form a 3- to 6-membered, carbocyclic ring,
- R17 is H or methyl,
- Z12 is an imidazolyl, 1,3,4-triazolyl, oxazoledionyl hydantoinyl radical,
- X13 is chlorine or alkoxy, and
- R18 is alkyl.
A color photographic material which comprises at least one light-sensitive silver halide emulsion layer, and which, in at least one layer which contains a color coupler, contains at least one homo- or copolymer which comprises a monomer unit of formula (II)
- wherein the monomer unit (II) amounts to at least 10% by weight in copolymers, and which further comprises an image stabilizer of formula (IV)
- wherein
- Ra, Rb, Rd, Re independently are H, alkyl, aryl, aralkyl, acylamino, acyl or halogen and
- Rc is alkyl, aryl, aralkyl, acyl or acylamino.
